3D打印又称增材制造，是一种新兴的成型技术。在制备复杂结构，节约材料等方面具有突出优势，伴随着计算机技术的发展，3D打印在众多领域都得到了快速发展，并越来越都受到人们的重视和青睐。其本身也被看作是第三次工业革命的标志。在3D打印技术中，有一类是基于光固化技术的3D打印。因为具有成型速度快，精度高，技术工艺成熟等特点，在产品设计，医疗，模具等行业都有越来越广泛的应用。其所使用的材料被称为光敏材料或光敏树脂，是一种以光固树脂为主要原料的液体混合物。能够在曝光时（UV紫外线），迅速固化成型。
3D打印有一个重要应用，就是在牙科领域。由于牙齿外形的唯一独特性，并不适用大规模和批量化为特点的传统制造。非常适合3d打印发挥其独有的优势。
受限于我们的知识和专业，我们只介绍光固化相关及牙科相关的3D技术。

3D printing, also known as additive manufacturing, is an emerging forming technology. It has prominent advantages in preparing complex structures and saving materials. With the development of computer technology, 3D printing has achieved rapid development in numerous fields and is increasingly valued and favored by people. It is also regarded as a symbol of the Third Industrial Revolution in itself. Among 3D printing technologies, there is a type based on photopolymerization technology. Due to features such as fast forming speed, high precision, and mature technological processes, it has increasingly extensive applications in industries like product design, medicine, and molds. The materials it uses are called photosensitive materials or photosensitive resins, which are liquid mixtures with photopolymerizable resins as the main raw material. They can quickly cure and form when exposed to light (UV ultraviolet rays). 3D printing has an important application in the dental field. Due to the unique individuality of the shape of teeth, traditional manufacturing characterized by large - scale and batch production is not applicable. It is very suitable for 3D printing to exert its unique advantages. Limited by our knowledge and expertise, we will only introduce 3D technologies related to photopolymerization and dentistry.
